Question

Factorise 2x^2/49-162y^2
plz write all the steps
I WILL MARK IT AS "BRILLIANT"
ANSWER IS 2(x/7-9y)(x/7+9y)​

Answer 1

$2( \frac{x}{7} - 9y)( \frac{x}{7} + 9y)$

Next, simplify the product. The equation will then become:

$2( \frac{x {}^{2} }{49} - 81y)$

Multiply it now by 2 and the finql answer is:

$\frac{2x {}^{2} }{49} - 162y$
